.CATAPULT FOR PROPE'LLING BOOMERANGS.

SPECIFICATION forming part of LettersPatent No. 510,936, dated December19, 1893.

Application filed March 11, 1893. Serial No. 465622. (N0 model.)

To all whom it may concern.-

Be it known that I, CHARLES W. RENEAR, a citizen of the United States,residing at-Stockton, in the county of San Joaquin and State ofCalifornia, have invented certain new and useful Improvements in Toysfor Propelling Boomerang-s; and I do declare the following to be a full,clear, and exact description of the companying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in boomerang throwers or catapults;and its noveltywill be fully understood from the following descriptionand claims when taken in connection with the annexed drawings,in which-Figure 1 is a side elevation of my improved boomerang thrower. Fig. 2 isa top View of the same with the boomerang in position for discharging,showing it in position before discharging the boomerang, the dottedlines indicating the position of the mechanism and boomerang afterdischarge. Fig. 3 is a detail sectional view through line X X Fig. 1.Fig. 4 is a detail sectional view of the bracket C through line X XFig. 1. Fig. 5 is a side view of the boomerang.

In the drawings, similar letters of reference indicate correspondingparts through out the several views, referring to which-- A, indicatesan ordinary wooden handle, secured to a head B, preferably of cast iron,which is provided with a bracket or brace O,

I having a projection E, which projection is provided with a groove Fand with a hole F, for

and H, extend outwardly in a plane approximately at right angles to thatof the handle; A, and they merge at their outer ends into coil springs Jwhich in turn merge into the forwardly or inwardly extending arms orwires G, H. These arms or wires carry a and replaced at pleasure of theperson using .the device.

The springs J, are held in position by means of a bolt or rivet N, andare kept at a suitable distance from one another by means of a washer 0,located between the contiguous parts of the springs J. The head B, oneither side, is provided with holes P for the purpose as will loo-shown.

Q, are lugs, provided with holes or guides, suitablysituatedin anirregular line with and between the holes P, into which holes and lugs Pand Q, are inserted the ends of awire holder B, provided with aspring-jaw, which is adapted to hold my improved boomerang, S, in anydesired horizontal position. By this construction it will be readilyperceived that the boomerang holder B, may be adjusted with respect tothe path traversed by the striker K, so as to give the boomerangdiiferent flights.

The boomerang S, is made of aluminum, and is therefore very light andstrong, and not liable to cause any accident should it strike any frailobject in its flight. A flat bar of metal may be substituted for thewires G and H if desired.

The mode of operating my improved boomerang thrower, is as follows: Thehandle A, is grasped by the left hand of the person using the same, whowith his right hand,grasps the cube K, and draws it back, as'shown inFig. 2, and holds it in such position by placing the thumb of the lefthand between said cube and the bracket 0. iVith the right hand, theboomerang is placed in position, as shown in Fig. 2. The cube is thengrasped with the thumb and index finger of the right hand, and is drawnback a distance relative to the desired flight of the boomerang, and isthen released and springing forward, strikes the boomerang and propelsthe same through the air,,t0 a certain point, at which it will turn andfly back to near the point from whence it started.

The dotted lines in Fig. 2, show the position of the boomerang, cube Kand wire G, immediately after the release of the striking cube.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a boomerang thrower or catapult, the combination with a handle,and a holder R, connected with the handle and having a spring adapted toclamp and hold the boomerang; of a spring actuated arm connected withthe handle and'disposed in a plane at right anglesthereto; the said armbeing provided with a striker adapted to engage theboomerang,substantially as and for the'purpose set forth.

2. In a boomerang thrower or catapult, the combination with a handle,and a spring-actuated throwing arm connected with said handle;f'of ,adevice for holding the boomerang in a position to be struck by thespring actuated arm; the said holding device being adjustably connectedwith the handle so as to permit the boomerang to be placed in variouspositions with respect to the path traversed by the spring actuated arm,substantially as and for the purpose set forth.

3. In a boomerang thrower or catapult, the combination with a handle,and a device con nected with the handle and adapted to hold theboomerang in a position to be struck; of the wires G, H, connected attheir inner ends with the handle, the coiled springs J, formed at theouter ends of the wires G, H, the wires G, 1-1, extending from thecoiled springs J, toward the handle and having angular barbs at theirinner ends adapted to engage and hold a striking piece, thesaidstrikingpiece, and a clamping band embracing the wires G, 1-1, andadapted to slide upon the same, substantially as specified. 7 Y
